Apologies, I misread.If you don't have a host yet, some of them will let you give them that file to run themselves on one of their servers to make sure they're compatible with version 4. (It would be in their best interest to do so, if they're a good Host.)As to the minimum specs, please see the bottom left of this page:https://www.invisionpower.com/buy/self-hostedPHP 5.3+ (5.4 recommended)All default extensionsGD2 extensionmbstring extensionMySQL 5.1+ (MySQL 5.6+ is recommended)

Yes, although our automated system will install version 4 by default as soon as your transaction is approved.Just file a ticket to Hosting asking for version 3.4.8 instead, and we can change that to version 3.4.8 for you.
